Answer:
Assuming you mean the diameter is 4 cm:
perimeter = 10.28 cm
Step-by-step explanation:
full circle perimeter = πD = (3.14)(4) = 12.56 cm
half circle = 12.56 cm/2 = 6.28 cm
flat side = 4 cm
6.28 cm + 4 cm = 10.28 cm

What is hypotenuse?"It is the longest side of the right triangle."
What is Pythagoras theorem?"For a right triangle,
[tex]a^2+b^2=c^2[/tex], where c is the hypotenuse of the right triangle and a, b are other two sides of right triangle."
For given question,
We need to write a function that models the relationships among x, y, and r.
Consider a right triangle ABC.
where AB = x, BC = y and hypotenuse AC = r
Using Pythagoras theorem,
[tex]x^{2} + y^{2} =r^{2}[/tex]
above function defines the relationships among x, y, and r.
Now we solve above equation for 'r',
[tex]\Rightarrow r^2=x^2+y^2\\\\\Rightarrow r=\sqrt{x^2+y^2}[/tex]
Therefore, the function that models the relationships among x, y, and r is [tex]r=\sqrt{x^2+y^2}[/tex]

Look below!
Step-by-step explanation:
1. What is the horizontal distance that your bridge must span to clear the ravine? (1 point)
150 feet.
2. Write a function that models the relationships among x, y, and r. (Hint: Use the Pythagorean theorem.) Then solve the equation for r in terms of x and y. (3 points: 1 point for the correct Pythagorean setup, 1 point for work, 1 point for the solution)
Pythagorean theorem—>a^2+b^2=c^2
a and b are the legs, while c is the hypotenuse.
x^2+y^2=r^2
Take the root of both sides
r=√x^2+y^2
The length of a rectangular box is 1 inch more than twice the height of the box, and the width is 3 inches more than the height. If the volume of the box is 252 cubic inches, find the dimensions of the box. length in width in height in
Answer:
height be 4 in
length be 9 in
ANd, the width be 7 in
Step-by-step explanation:
Let us assume the height of the box be x
So the length would be 2x + 1
And, the width be x + 3
As we know that
The volume of the rectangular box = length × width × height
252 = (2x + 1) × (x + 3) × (x)
252 = (2x^2 + x) × (x + 3)
252 = 2x^3 + 6x^2 + x^2 + 3x
2x^3 + 7x^2 + 3x = 252
2x^3 + 7x^2 + 3x - 252 = 0
after solving this
x = 4
So height be 4 in
length be 9 in
ANd, the width be 7 in

Kayla earns $10.75 per hour babysitting. How much will she earn for a job that lasts from 8:30 a.m. to 4:30 p.m.
Answer:
$86
Step-by-step explanation:
8 hours times 10.75
Answer: $86.00
Step-by-step explanation:
8 to 9 , 9 to 10, 10 to 11, 11 to 12, 12 to 1 , 1 to 2, 2 to 3 , 3 to 4 come up to 8 hours.
4:00 to 4: 30 is half hour.
So 8:00 to 4: 30 come up to 8 1/2 hours (eight and half hours ).
8:30 am to 4:30 pm= 8 hours.
then it is $10.75x8=$86.00

a dance club spent $922 on 40 items.The item include some hats and pairs of shoes.Each hat cost $19 and each pair of shoes cost $25.How many pairs of shoes did the dance club buy?
1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.

Answer :
to find area of the square = 6 to the power 2
to find the area of the rectangle = (5x + 12) * 5x
therefore,
square's area = 36
rectangle's area = 5x*5x + 12 * 5x
= 25x * 60x
Now we have to find the sum of both the areas,
so, 36 + 1500 = 1536

Answer:
Number of 45° angles = 1
Number of 90° angles = 1
Number of 135° angles = 3
Step-by-step explanation:
From the figure attached,
Angles in Figure D are,
Measure of angle A = 45°
Measure of angles B = 45° + 90° = 135°
Measure of angle C = 90° + 45° = 135°
Measure of angle D = 45° + 90° = 135°
Measure of angle E = 90°
Therefore, number of 45° angles = 1
Number of 90° angles = 1
Number of 135° angles = 3
Can a trangle have lengths of 1 , 1 and 6
Answer: No it can't
You can prove this with Pythagorean theorem. (a^2+b^2=c^2) In this case, 6 is the highest number so we know it has to be the hypotenuse. So plug it into the equation, 1^2+1^2=6^2, and simplify. You will get 2=36, and we know that is not true, so a triangle can't have the lengths of 1, 1, and 6.

Choose the correct graph of the function Y = Vx+1
Answer:
The graph for y=[tex]\sqrt{x}[/tex]+1 looks like this. Hope this helped you :D
Step-by-step explanation:
The required graph of y = √x + 1 is a curve that starts from the point (0,1) and rises continuously as x increases.
What is the graph?The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The equation y = √x + 1 represents a simple algebraic function in which the value of y is dependent on the value of x.
When we plot this function on a graph with x on the horizontal axis and y on the vertical axis, we get a curve that starts from the point (0,1) and continues upward as x increases.
At x=0, the value of y is 1. As x increases, the value of y increases as well, but at a slower rate because of the square root function. As x approaches infinity, the value of y also approaches infinity, but again at a slower rate than a linear function.
Since the domain of the function is all non-negative real numbers (x ≥ 0), the graph of the function exists only in the first quadrant of the coordinate plane.
Overall, the graph of y = √x + 1 is a curve that starts from the point (0,1) and rises continuously as x increases.
